TROLLEY-IPOLE FASTENING.

Specification of Letters Patent.

Patented Jan. 12, 1909.

Application filed September 16, 1907. Serial No. 393,121.

To all whom it may concern:

Be it known that I, OLIVER L. SPRY, a citizen of the United States,residing in Des Moines, county of Polk, and State of Iowa, have inventeda new and useful Improvement in Trolley-Pole Fastenings, of whic thefollowing is a specification.

The object of my invention is to provide a means of fastening a trolleypole to the socket which may be speedily and easily operated and whichwill cause the trolley wheel to be in line with the wire when the poleis in line with the car.

Another object'is to produce such a means in a simple, durable, strongand inexpensive construction.

My invention consists of certain details of construction hereinafter setforth, pointed out in my claim and illustrated in the accompanyingdrawings, in which- Figure 1 shows a side elevation view of my means ofsecuring the pole to the socket; Fig. 2 shows a detail view of a portionof the pole to which the trolley wheel is secured; Fig. 3 shows a detailview of the lower extremity of the pole I employ: Fig. 4 shows a planview of my means of fastening the pole to the socket; and, Fig. 5 showsa longitudinal section of the same.

Referring to the accompanying drawings, the reference numeral 10 is usedto indicate the standard in which the socket 11 is designed to besecured said standard being similar in construction to any of those incommon use and the usual means of mounting the socket in the standard isalso employed. The upwardly extending portion of the socket is providedwith a receptacle 12 designed to receive the pole 13. At the lowerextremity of the receptacle 12 I have provided a lug 14 designed toengage a groove 15 in the lower extremity of the pole when the parts arejoined. I have also provided orifices 16 in the receptacle 12 andcorresponding orifices 17 in the pole said orifices being designed to bein line with each other, when the parts are joined, and designed toreceive a retaining pin 18, as fully mediately over the lug 14 when thepole will move further into the receptacle the groove engaging the lugand firmly holding the pole in position. The position of the pole atthis time is, by construction, such as will cause the trolley wheel tobe in line with the wire when the pole is in line with the car. Theretaining pin 18 is then placed in position as shown in Fig. 5 of thedrawing thus completing my fastening.

Having thus described my invention what I claim and desire to secure byLetters Patent of the United States is:

In combination with a standard formed with a socket, a short lugintegral with the standard and extending lengthwise of the socket and atubular pole received in said socket and formed with a peripherallengthwise slot at its inner end, said pole at its inner end seating onthe base of the socket and receiving said lug in its slot, said lugprojecting on the interior of said tubular pole, said socket and polebeing formed with openings, and a pin passed through said openings.
